✦ Synopsis

This paper is concerned with the design of reconfigurable control laws for fault-tolerant systems. From the control design point of view the issue of performance robustness during the system normal operation versus failure sensitivity at the time of a system component failure is addressed. To achieve a balanced design, a parametrized set of controllers satisfying a prescribed performance level is first constructed, and then the parameter is optimized under a detection criterion that sensitizes the measurements to some specific failures. An example involving aircraft surface impairment is given to explain the procedure for obtaining the optimized design.
